Ins. Code, § 706.7

As used in this section, the term “reciprocal state” means a state the laws of which prohibit an insurer domiciled therein from insuring the lives or persons of residents of, or property or operations located in, the State of California unless it then holds a valid and subsisting certificate of authority issued by the Insurance Commissioner of this state. This prohibition may be subject to the exceptions herein set forth.

Subject to the exceptions herein set forth, a domestic insurer shall not enter into a contract of insurance upon the life or person of a resident of, or property or operations located in, a reciprocal state unless it is authorized pursuant to the laws of that state to transact such insurance therein. The commissioner shall, every four years, mail notice to every domestic insurer, specifying the reciprocal states.

The exceptions to the provisions of this section are the following:

(a) Contracts entered into where the prospective insurant is personally present in the state in which the insurer is authorized to transact insurance when he or she signs the application.

(b) The issuance of certificates under a lawfully transacted group life or group disability policy, where the master policy was entered into in a state in which the insurer was then authorized to transact insurance.

(c) The renewal or continuance in force, with or without modification, of contracts otherwise lawful and which were not originally executed in violation of this section.
